Shaky wake-up

The 4.4 magnitude jolt woke up many and sent others running for cover, but luckily no damage or injuries have been reported.

The quake hit at 6:25 local time this morning, providing a shaky wake-up-call for millions across southern California.

The earthquake was the first significant rattle in Los Angeles in more than five years. The quake was reported at a depth of about five miles, a typical depth for the region that will make it difficult to determine the fault on which the quake occurred, Caltech seismolgists said.

Minor delays were reported on Metro rail lines, but normal service resumed after officials reported no damage. The California Highway Patrol reported no damage to Los Angeles' roads.

The quake's energy probably produced a "rolling" feeling for people in the Los Angeles basin. Residents in the Santa Monica Mountains, near the center of the quake, likely felt a sharp jolt, said Egill Hauksson, a seismologist with Caltech.
